DUMP CAR.

Application filed January 25, 1923. Serial No. 614,797.

This invention relates 'to improvements in dump cars.

One object of the invention is to provide in a (lump car, efiicient and relatively inexpensive means for retaining the discharge door in a partially closed position and thereafter supporting and locking the same in closed position.

A specific object of the invention is the provision of a door looking arrangement having portions thereof utilized to strengthen certain parts of the car construction which have heretofore been liable to injury.

In the drawings forming a part of this specification Fig. 1 is avertical, transverse, sectional view taken through a portion of a W-type hopper car illustrating my improvements in connection therewith. Fig. 2 isa side elevational View of a portion of the same car showing the discharge door in fully closed locked position. Fig. 3 is a view taken on a line corresponding substantially to line 3-3 of Fig. 2. Fig. 4 is a fragmentary side elevational view of the car illustrating the discharge door in partially closed osition. Fig. 5 is a perspective view of the oor brace extension. Fig. 6 is a perspective view of a modified form of door brace extension.

Referring to the drawing, 10 denotes one of the side walls of the car, 11 a side stake, 12 one of the center sills, 13 the longitudinally extending ridge sheet over the center sills, 14 the transversely extending ridge sheet'between the sets of hoppers, 15 one of the hopper bottom sheets sloped downwardly from the end of the car toward the center, 16 an inner hopper side sheet, and 17 an outer hopper side sheet, the latter being sloped downwardly and inwardly towardsthe center line of the car. As will be understood by -those skilled in the art, there are-four hoppers similar to the one illustrated, two on each side of the center sill and arranged in pairs extending transverse- 1y of the car.

The hopper side sheets 16 and 17 are suitably flanged along their edges surrounding the discharge opening to provide the necessary strength as indicated at 18 and 19 respectively, and the lower edge of the bottom sheet 15 is reinforced by a transversely extending angle 20 secured to the underside thereof. Each hopper discharge opening is adapted tobe closedby a sheet metal door as indicated at 21, the latter being hinged along their upper edges to swing about axes extending transversely of the car and reinforced at theside edges by flanges 21*. In the. arrangement shown, each door 21 is hinged to brackets 22 which are riveted to the transversely extending ridge sheet 14 which is there reinforced by means of angle 23.

Secured to each transversely alined pair of doors 21, adjacent the free edges thereof and parallel thereto, is a beam 24. The beam 24 is secured to the transversely alined doors of a set so that the latter are operated in unison. Secured to each end of the beam 24 is a flanged extension A, each preferably formed of a plate pressed in the form of a channel and of reduced depth as it passes under the flanges 21 of the door 21. Each said extension A has the web 25 thereof secured to the beam 24 and one of the flanges 26 secured to the door by means of rivets passing through the beam 24 and door plate 21. The opposite flange 27 is curved, preferably on a radius, the center of which coincides with the pivotal axis of a latch B, hereinafter described, the latter having a correspondingly curved shoulder 28 whereby, when the door is in closed position, the latch will securely hold the same. The latch 13 is pivoted to a bracket C which is secured to the car body and with the latch co-operates a cam D, as hereinafter specifically described.

Said bracket C rests upon and fits against the angle 20 which is extendedoutwardly beyond the hopper side walls 17, thus providing ledges on which the brackets rest, it being understood that I employ a latch at each side of the car, only one side however being shown in the drawing. The bracket C, preferably in the form of a casting, has an inner wall 29 lying against the sloping side sheet 17 and secured thereto by means of a rivet 30. The bracket casting C is also provided with an out-erwall 31 disposed in a substantially vertical plane and spaced a short distance from the inner wall 29, said inner and outer walls being connected with a transversely extending wall 32 of arcnate shape and a wall 33 parallel with and secured to the outstanding flange of the angle iron 20 b means of a rivet In addition, the brac et is formed with av fian e 35 extending downwardly and secured to the depending flange of the angle iron 20 by means of .a rivet 36.

The latch member B is pivotally mounted on the bracket casting by means of pivot 37 and lateral outward movement of the said latch member is restrained by means of a. flange 38 formed on the outer wall and inward lateral movement by means of a web 39 formed on the end of a boss 40 extendin outwardly from the inner wall 29. Sai boss 40'is recessed at 41 to accommodate the head of the pin 37 which is inserted therein before the casting C is placed on the car. With this arrangement, it will be observed that the casting G securely unites the hopper side sheet 17, the hopper bottom sheet 15 and the bracing angle 20, at the lower corner of the hopper, thereby preventing the hopper side sheet from tearing out or rusting out at this point, which has been a source of difliculty in cars of this type heretofore.

The locking cam D is pivotally supported between the outer wall 31 of the bracket C and the sloping hopper side wall 17 on a rivet or pin 42, which not only acts as a pivot for the cam D but also assists in securing the bracket C to the hopper sheet. Said cam D is of Well known form and engages with a curved surface 43 formed on the latch member B. A ferrule 44 preferably formed of a section of commercial pipe is interposed between the sloping hopper side sheet 17 and the cam D, thereby maintaining the latter in. alignment with the latch B.

The outer end of the latch B is beveled as indicated at 144 so as to act as a guide to lift the said latch when the doors are moved to closed position, said edge 144 being engaged by the flanged extension A, as will be understood, the latch dropping into looking position under gravity when the curved flange 27 on the extension A has passedbeyond the locking face 28 of the latch B.

It is sometimes desirable to close the doors in a series of operations and in order to maintain the door in a partly closed position, I have provided in the web 25 of the extension A, a recess 45 within which the end of the latch B may drop and temporarily maintain the door in a nearby closed osition. In its preferred form the loc (ing face 28 of. the latch B is caused to engage the edge 46 of the perforation formed in the web 25 of the extension A. The relative position then assumed by the parts with the door partially closed is clearly indicated in Fig. 5 where the beveled end of the latch is shown as extending within the recess 45. Said recess is preferably formed by punching a relatively narrow slot in the plate and thereafter depressing the metal adjacent thereto in a downward direction as indicated at 47.

I have shown in Fig. 6 a modified construction wherein the recess in the web for the purpose -ofreceiving. the latch is formed by punching a rectangular shaped hole therein as indicated at 48.
